The following options can be configured on the CBUS I/O pins. These options are all configured in the
internal MTP ROM using the utility software FT_PROG, which can be downloaded from the
www.ftdichip.com. The default configuration is described in

IO Pad is tri-stated
Output a constant 1
Output a constant 0
Output is low after the device has been configured by USB, then high
during USB suspend mode. This output can be used to control power to
external logic P-Channel logic level MOSFET switch.
NOTE: This function is driven by an open-drain to ground with no
internal pull-up, this is specially designed to aid battery charging
applications. UMFT240XE connects an on-board 47K pull-up on each
CBUS and DBUS signal.
Transmit data LED drive – open drain pulses low when transmitting data
via USB.
Receive data LED drive – open drain pulses low when receiving data via
USB.
LED drive – open drain pulses low when transmitting or receiving data
via USB.
Goes low during USB suspend mode. Typically used to power down an
external logic to RS232 level converter IC in USB to RS232 converter
designs. Deactivate SLEEP# option for when connected to a dedicated
charger port, this can be selected when configuring the MTP ROM. When
this option is enabled SLEEP# is driven high when FT240X is connected
to a Dedicated Charger Port.
24 MHz Clock output.**
12 MHz Clock output.**
6 MHz Clock output.**
Battery Charge Detect indicates when the device is connected to a
dedicated battery charger host. Active high output. NOTE: Requires a
10K pull-down to remove power up toggling.
Active low BCD Charger, driven by an open drain to ground with no
internal pull-up (4.7K on board pull-up present).
Synchronous and asynchronous bit bang mode WR# strobe output.
Synchronous and asynchronous bit bang mode RD# strobe output.
Input to detect when VBUS is present.
Toggle signal which changes state each time a USB SOF is received
Active Low input, prevents the chip from going into suspend.
